Is this the correct/best way to test whether a string begins with a digit in
XSL 1.0?

    <xsl:when test="string(number(substring($input-name, 1, 1))) != 'NaN'">

I guess using a regular expression in XSL 2.0 would be the best approach, but
unfortunately I'm constrained to using MSXSL and hence XSL 1.0 at the moment.
